As we all know, the brakes of electric vehicles play a great safety role. But sometimes the brake power failure or brake handle failure will also cause the car not to go, here we mainly explain the principle and connection method of the brake power off function line of the electric vehicle.
Generally, there are two kinds of brake power off of electric vehicles, one is high-level brake, and the other is low-level brake.
First of all, let’s talk about high-level brakes, generally scooters are high-level brakes, normal (no brakes), the car is powered on when the switch has no voltage, and the voltage after braking is 12 volts (some are connected to the total voltage of the electric vehicle). The principle is to input a voltage signal to the high-level brake line of the controller, and the original part of the controller is turned on to realize the brake action and light the rear taillight.
Low-level brake, the controller low brake line output voltage signal, through the power off switch, closed conduction, complete the braking action.
